IMPROVEMENT IN COMBINED PLOWS.

Specification forming part of Letters Patent No. 4,7115, dated September5, 1846.

To all whom it may concern:

Be it known that we, JOHN KRAUsEE and CYRUS KRAUSER, of the borough ofReading, in the county of Berks and State of Pennsylvania, have inventedcertain new and useful Improvements in Plows, used in plowing corn,potatoes, Sac.; and lwe do hereby declare thet'ollowing to be full andexact description ot"- the same, reference being had to the accompanyingdrawings, making a part ot' this speoilication; and to enable othersskilled in the art to make and use our invention, we will proceed todescribe its construction.

Figurel represents' the frame of the plow, which is somewhat in the formot' a square, the front part, however, being less in width than the hindpart. The hind cross-beam, A, is tenoned into the side pieces, B B, sothat the latter project beyond said cross-piece any desirablelength. Thetongue passes the front cross-piece at right angles and terminates'in amortise out in the hind cross-piece. The tongue is fastened to the frontcross-piece by means ofa bolt. In each end of the beam A there is alongitudinal opening about four inches in length placedon the inside ofthe side pieces, B B. SaidA openings are large enough in width toreceive the shaft of the stand, and'over each of these longitudinalopenings is slipped a metallic box, H, of the exact size ofthe beam A,having a round hole in the bottom, and also one in the top. The shaft ofthe stand is represented in said hole with a pin sticking through it.Said boxes being moved to and fro on the beam A, the holes move in aline withthe longitudinal openings, both of which are shown ato o in'Fig. 5. The bottom of the box is the same as the top, (seen in theiigure,) and its sides of the same width as those parts of the top whichtouch the edges of the beam A.

Fig. 2 represents a hind view of the plow. C Gare two upright stands orshares of a given breadth from the bottom upward to about onethird theirheight. The remainder is of an optional breadth. D D are two knees orbraces cast to the outside of the stands. They may also be cast on theinside, or one may be cast upon each edge of each stand, the top ofwhich brace rests flat against the bottoni of the side pieces, B B, whenthe shaft of the stand is introduced into the holes in the Inetallicboxes H H. These braces serve to give additional strength to the stands,and alsoof keeping them in any given position. For this purpose, asrepresented in Fig. 4, (which figure represents a top view of the brace,u being the shaft ofthe stand,) at a the end of the brace at thel topmay be made of any breadth, having a number of holes cast in it, one ofwhich, whenever the stands are turned inward or outwardl so as to form agreater or less angle with each other, is made to correspond to asimilar hole, b, in the frame of the plow, through which a bolt ispassed to keep the stand securely and tirmly in its place.

lt should be observed that the above-inentioned holes in thc top of thelbrace are cast in the circumference of a circle, the center of which isn, Fig. 4.- On the inside ofthe stand, and at the bottom, is any ironplate, in length something more than the breadth of the stand, havingtwo small longitudinal openings at convenient points in their length,and also in their breadth, so that said plate projects beyond the bottomof the stand aboutan inch. A bolt is passed through each opening into ahole in the sta-nd, by means of which they are fastened together. Theplate can be moved backward and forward in a line with the bolts, and inorder to elevate or depress said plate the bolts are taken ont andpassed through a hole higher or lower on the stand, as the case mayrequire.

Fig. 3 represents a side view of the form ot' the stand, D being the.brace, and a that part ot' it already referred to.

What we claim as ot' our in vcntion, and wish to secure by LettersPatent, is

1. The knee or brace cast on the stand, as herein explained.

Y 2. The longitudinal openings o o, together with the metallic boxes HH.
